CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 17/068,757, filed Oct. 12, 2020, titled “Methods and System for Providing Scene Layouts During a Network Conference,” the entirety of which is incorporated herein by reference.

FIELD

The exemplary embodiments of the present invention relate to the field of network communication. More specifically, the exemplary embodiments of the present invention relate to conducting a network conference.

BACKGROUND

With the increasing popularity of digital electronics and network communications, real-time interactive network conferences (or meetings) have become more popular. For example, network conferencing applications now allow people to communicate with each other from remote locations to exchange audio and video in real time.

During a network conference, each meeting attendee can transmit video and audio signals to other attendees. A typical conferencing system is configured with a camera that captures an image of a conference attendee and transmits this image to other attendees. Typically, attendee images are displayed on a non-descript background. However, network conferences are now being conducted for all types of events, such as holiday parties, weddings, and other types of events. Thus, it is desirable to have a mechanism to customize how images of the conference attendees are displayed to add context to the meeting and enhance user experience.

SUMMARY

In various embodiments, system and methods are disclosed for providing scene layouts during a network conference. In an embodiment, a host of a network conference identifies a customizable scene layout to be used to conduct the network conference. For example, the host selects the scene layout from layouts available at a conference server. The scene is distributed to the conference attendees. In an embodiment, the host passes a universal resource locator (URL) to the conference attendees that identifies a location from which the scene can be downloaded. The scene comprises customizable background layers, foreground layers, and video layers as well as other features. The video layers include video areas or regions, such as video boxes. The host assigned the video boxes to the conference attendees. During the conference, each participant displays the scene and each video box of the scene displays an image or live video stream of an attendee assigned to that box. Thus, the scene operates to add context to the meeting and enhance user experience.

The host can customize the scene by modifying various aspects of the scene. For example, the host can modify the background, foreground, or video regions. The modifications of the scene by the host are propagated to the attendees. In an embodiment, an attendee can send a request to the host to modify the attendee's video region. For example, the attendee can request to changes the size, shape, location, orientation, features, and/or background of the attendee's video region. The host can authorize or decline the requested changes.

In an embodiment, the scene also includes video effects, reactions, accessories images, text areas, and accessory selectors. For example, the video effects can include effects that are applied to the video image of an attendee. The effects can be fixed within the video region of the attendee or pinned to allow the effect to move with the image of the attendee.

In an embodiment, a method for providing a scene layout for use by conference participants during a network conference is disclosed. The method includes identifying a conference host and conference attendees from the conference participants, identifying a scene layout selected by the conference host, and distributing the scene layout to the conference participants. The scene layout includes a plurality of video areas. The method also includes assigning selected video areas of the scene layout to selected conference participants, respectively, receiving video streams from the selected conference participants, and displaying the scene layout so that the video streams from the selected conference participants are displayed in their associated video areas, respectively.

In an embodiment, a host apparatus is provided for conducting a network conference with conference participants that include the host apparatus and one or more attendee user equipment (UE). The host apparatus comprises a transceiver to communicate with the one or more attendee UE. The host apparatus also comprises a processor that performs functions that include identifying a scene layout that comprises a plurality of video areas, distributing the scene layout to the one or more attendee UE, and assigning selected video areas of the scene layout to selected conference participants, respectively. The processor also performs functions that include receiving video streams from the selected conference participants, and displaying the scene layout so that the video streams from the selected conference participants are displayed in their assigned video areas, respectively.

In an embodiment, a non-transitory computer readable medium is provided on which are stored program instructions that, when executed by one or more processors, cause the one or more processors to conduct a network conference with conference participants that include a host apparatus and one or more attendee user equipment (UE) by performing operations of: identifying a scene layout that comprises a plurality of video areas; distributing the scene layout to the one or more attendee UE; assigning selected video areas of the scene layout to selected conference participants, respectively; receiving video streams from the selected conference participants; and displaying the scene layout so that the video streams from the selected conference participants are displayed in their assigned video areas, respectively.

FIG. 1 shows a diagram illustrating a communication network 100 configured to conduct a network conference with a configurable scene layout. The communication network 100 comprises first user equipment 102, which is referred to as a host UE that acts as a host for the network conference. The network 100 also comprises attendee user equipment (A1-A3) that participant in the network conference. The conference participants (e.g., host 102 and attendees (A1-A3)) are configured to communicate with each other utilizing a conference system server 104 and communication network 106. In an embodiment, the conference server 104 stores a plurality of scene layouts 108 that can be purchased or licensed for use during a network conference. In another embodiment, the host can create a custom layout 124 that is sent to the server 104 (indicated at 126) when the conference is initially setup. The custom layout 124 is stored at the sever 104 and made available to the attendees in the same way as the pre-defined layouts. An editor for creating customized layouts is discussed in greater detail below. In an embodiment, the communication network 106 comprises a wired communication network, a wireless communication network, or a combination of wired and wireless communication networks.

During a conference, the host 102 communicates with the conference server 104 to obtain a scene layout for use during the network conference. For example, the host obtains the scene layout 110 that is transmitted from the conference server 104 to the host UE 102 over network path 112.

An exemplary depiction of the scene layout 110 is shown on the display of the host 102. The scene layout 110 comprises a plurality of visual components that include a scene background 116 and video boxes or regions 118 in which video streams from the participants are displayed. For example, an attendee video stream comprises an attendee background 120 and an image 122 of the attendee. A more detailed description of the various scene components is provided below.

To distribute the scene 110 to the attendees, the host 102 transmits a universal resource locator (URL) 112 associated with the scene to the attendees (A1-A3). For example, the URL is provided to the host UE with the scene layout 110. Each attendee uses the URL 112 to obtain the scene layout 110 from the conference server 104. The host 102 retains control over the scene layout 110 and can make adjustments or changes to the scene layout, and these changes are propagated to the scene layouts displayed on the UE of the attendees. For example, the host UE generates and outputs configuration parameters 128 that are distributed to the attendees. The configuration parameters 128 assign the attendees' video stream to selected video regions within the scene. The configuration parameters 128 also control various other aspects of the scene. The attendees also are allowed to change characteristics related to the presentations of their own video streams with permission from the host. For example, with permission from the host UE 102, an attendee can transmit its own set of configuration parameters that adjust the regions of the layout associated with the attendee, for instance, the attendees' video region within the scene layout. Thus, the scene layout 110 forms a common visual presentation for the network conference that adds context to the meeting and enhances user experience.

In various exemplary embodiments, scene layouts are provided for use during network conferences by performing at least the following operations.

1. A host UE obtains a scene layout to be used for a network conference. In an embodiment, the host UE obtains the scene layout from a conference server. In another embodiment, a custom scene layout is created on the host UE and passed to the network server for distribution to conference attendees.

2. The scene layout is distributed to the conference attendees. For example, in an embodiment, the host sends to the attendees, a URL that identifies the network location of the scene layout.

3. The attendees obtain the scene layout and display this layout on their own UE during the conference. The scene layout includes video boxes or regions that are assigned to display the video streams from the host and the conference attendees. For example, the host UE generates and transmits configuration parameters 128 that assign the video regions in the scene layout to the attendee video streams. Thus, the scene layout forms a common visual presentation for the network conference.

4. Changes to the scene can be made by the host or by an attendee with the host's permission. For example, the host can generate and transmit configuration parameters 128 to adjust the sizes or locations of the video regions within the scene. An attendee can obtain permission from the host to generate and send out its own configuration parameters to adjust the size of its own video box or to add video effects or backgrounds to the attendee's image.

Thus, all of the participants of the conference see the same scene layout with the attendees in the same screen locations and having the same video characteristics. More detailed descriptions of the various implementations and operations host 102, attendees (A1-A3) and conference server 104 to provide scene layouts during a network conference are provided below.

FIG. 3 shows an exemplary detailed embodiment of scene components 300 that are used to construct a scene in accordance with various exemplary embodiments.

In an embodiment the scene construction begins with one or more background layers 302. The one or more background layers can be used to incorporate various images, pictures, fill regions, decorations, or any type of visual images that can be placed on the background layers. Unused portions of the background layers can be transparent so that images on various layers will show through when the layers are assembled into a set.

The scene construction also includes video layers 304 that are used contain various video areas, regions, or boxes in which participant video streams will be placed. Each video region includes an identifier that can be used to identify the region when assigning the region to a video stream of a conference participant.

The scene construction also comprises one or more foreground layers 306 that can be used to incorporate various images, pictures, fill regions, decorations, or any type of visual images. Unused portions of the foreground layers can be transparent so that images on various layers will show through when the layers are assembled into a set. The foreground layers can be used to provide borders, frames, or any other visual decoration in order to construct a foreground image. For example, the foreground layers 306 can form borders or frames that form an overlay to the video regions.

In an embodiment, the scene is constructed by combining a scene background 308 formed by the background layers 302, a video region 310 formed by the video layers 304, and a scene foreground 312 formed by the foreground layers 306. The video region 310 include video boxes for the participant image streams. For example, the video region 310 includes video box 314 that has an identifier that is used to assign that region to a participant video stream. In addition each video box may include a video background 316 that is received from the participant or provided by the scene layout.

The scene foreground 312 can include various decorations, such as a foreground frame 318. The scene background 308, video region 310, and scene foreground 312 are combined with a participant image 320 to generate a constructed scene 322. As illustrated in the constructed scene 322, the participant image or video stream 320 is placed in the video box 314 and foreground frame 318 forms a frame around the video box 314. The video region 310 and scene foreground 312 are placed on top of the scene background 308.

FIG. 4A shows an exemplary scene layout 400 constructed in accordance with various exemplary embodiments. The layout 400 comprises a scene background 402 and video boxes or regions, for example video region 404. Each video region comprises a video background, such as video background 406. Within each video box is a video stream of a participant to the conference. For example, the video stream 408 shows a conference participate. The scene layout 400 also comprised video effects, for example, the video effect 410 is a red beret hat, and the effect 412 are red glasses. These video effects are added to the video images of the participants. The scene 400 also comprises a reactions button 414, which can be used by participants to add reactions to the video conference.

FIG. 4B shows an exemplary scene layout 420 constructed in accordance with various exemplary embodiments. The scene layout 420 comprises background 422, which depicts a classroom image. The classroom image comprises rows of seating and in the seating are video regions (e.g., region 424), which contain the video streams from conference participants. The scene 420 also comprises video effects. For example, colored glasses 426 are added to one of the participant images as an accessory image 216 or video effect 208.

FIG. 5 shows an exemplary host apparatus 500 configured to provide a scene layout during a network conference. For example, the host apparatus 500 is suitable for use as the host UE 102 shown in FIG. 1. The host apparatus 500 comprises processor 502, memory 504, camera interface 506, display interface 508, instructions 510, scene storage 512, and transceiver 514 all connected to communicate over data bus 516.

During operation, the processor 502 executes the instructions 510 to perform the functions and operations of the host apparatus. For example, the processor 502 controls the camera interface 506 to receive a video signal 518 from a camera mounted at the user equipment. The video signal contains an image of the host user. The display interface 508 is configured to output display information 520 to a video display that is part of the host apparatus.

The processor 502 also receives user input 522 and uses this input to perform various functions of the apparatus. The transceiver 514 is used by the processor 502 to transmit and receive information during the network conference. For example, the processor 502 uses the transceiver 514 to transmit a scene request 524 to the conference server to request a particular scene layout for use during a video conference. For example, the scene request 524 is transmitted to the server 104 shown in FIG. 1. The server responds by sending the requested scene layout 526, which is received by the transceiver 514 and stored in scene storage 512. In an embodiment, the scene layout 526 is sent with a URL that identifies a location of the scene.

The processor 520 then uses the transceiver 514 to sends out the scene URL 528 to the conference attendees. Each attendee uses the URL to retrieve the scene layout 526 and display the scene layout on their respective user equipment. The processor 522 can make various adjustments and modifications to the scene as well assign the attendees to video regions that are configured within the scene.

Once the processor 502 completes any modifications or customizations of the scene, the processor outputs scene configuration information 530 to the attendees to allow those modifications to be reflected in the scenes displayed at the user equipment. In addition, the configuration information 530 includes assignments that assign participants to video regions within the scene. For example, each video region includes an identifier and the processor 502 assigns conference participant to the video regions using the region identifiers. The processor 502 also communicates with attendees using the configuration parameters 530. For example, the processor 502 can use the parameters 530 to grant permission to an attendee to modify its video region.

During the conference, the host apparatus exchanges audio/video (A/V) signals 532 with the conference attendees. The video signals received from the attendees are placed in the associated video regions of the scene, as demonstrated above. For example, the display interface 508 displays the scene layout with the participant videos included in the appropriate video regions. The camera interface 506 receives a host image signal 518 from a host camera and this host image is also placed in an host video region of the scene layout and displayed using the display interface 508.

In various exemplary embodiments, the processor 502 executes the instructions 510 to perform the functions and operations of the host apparatus 500. In an exemplary embodiment, the host apparatus 500 performs at least the following operations to provide a scene layout for use in a network conference.

1. The processor transmits a scene request 524 to a network server to obtain a selected scene layout.

2. The network server transmits the selected scene layout 526 to the host apparatus where it is received by the transceiver 514 and stored in the scene storage 512. The scene layout 526 includes an associated URL. In an alternative embodiment, a customized scene layout is generated by the host apparatus and transmitted to the server. The same process is used to retrieve the customized scene layout and associated URL as with the pre-defined layouts.

3. The processor 502 transmits the URL of the scene 528 to the conference attendees so that each attendee can retrieve the selected scene layout.

4. Processor retrieves the scene layout from storage 512 and outputs the scene to a video display using the display interface 508.

5. The processor 502 makes scene customizations to adjust scene components, such as background images, foreground images, or video regions within the scene layout. The processor also assigns video regions in the scene layout to conference participants. For example, each video region includes an identifier that is linked to a video stream of a particular conference participant.

6. The processor 502 propagates the scene changes and video region assignments to the conference attendees using scene configuration parameters 530. The attendees receive these parameters and update the scenes on their systems so that all the scene layouts match.

7. The video conference is conducted using the scene layout and images received from the attendees are displayed in the appropriate video regions within the scene.

8. Each attendee system also receives audio/video signals from all other attendees and the host, and displays the video images within the appropriate video regions of the scene layout.

9. Individual attendees can request modifications to their video image by sending a request to the host apparatus. The modifications can include changing the size and location of the video region for that attendee or the addition of special video effects to the video image of the attendee. For example, attendee requests are received as part of the configuration parameters 530.

10. The processor 502 either accepts or rejects the attendee request to modify its video image. For example, a host user reviews the request and provides user input 522 to the processor 502 indicating a decision on the request. If the changes are accepted, those changes are made within the scene and are also propagated to the other attendee systems using the configuration parameters 530. In another embodiment, the processor 502 transmits an authorization to the requesting attendee, which authorizes the attendee to send out its own configuration parameters that includes the adjustments to its own video region.
